Prosecute to restrict member that's lying (6)


I believe the answer is:

'lying' is the definition.

'prosecute to restrict member' is the wordplay.
'prosecute' becomes 'sue' (I've seen this before).
'to restrict' indicates putting letters inside.
'member' becomes 'pin' (pin is a kind of member**).
'sue' going around 'pin' is 'SUPINE'.

'that's' acts as a link.

(Other definitions for supine that I've seen before include "Recumbent", "Flat on one's back", "Laid-back", "Slow in acting", "Inert; on one's back".)

I've seen this clue in The Independent.
